  • Automatic Learning

    Continuously learns application-specific traffic patterns in production, reducing false positives over time without manual intervention.

  • Native Proxy Integration

    Runs as a module inside NGINX, Kong, or Envoy rather than as a separate proxy, eliminating additional network hops and latency.

  • Kubernetes Ingress

    Functions as a Kubernetes Ingress Controller with built-in WAF, providing security at the ingress layer without sidecars or service mesh.

  • API Protection

    Protects REST APIs against OWASP API Top 10 threats using the same ML engine, with automatic API discovery and schema enforcement.
